Patented Oct. 20, 1908.

To all'whom vMacy concern: -A n.

Be it known that I, DJALMA JULLIOT, a citizen of the Republic of France, residing at La Couture-Boussey, Eure, France, have in- A 'form a part of this specification.

ments. in the mechanism for My presenta invention relates to improveoperating the keys and covers of flutes or similar wind instruments vin order to simplify the fingering ofthe old style Boehm flutes, and to obtain truer notes with lessdificulty to the performer.

To that end the invention consists in 'cerf tain novel arrangements and combinations of keys, branch fin er pieces, ycon'nnimicating arms, shafts and s ecves es ecially arranged to produce the purposes as: ove outlined; all of which I Will proceed to definitely describe and then point out in the claims that which I believe to be novel.

In the drawing, Figure 1 is a diagrammatic view, showing the various keys, branch finger pieces, communicating arms, shafts and sleeves in their proper'- relation to each l preventing the other but developed on a plane. Figs. 2 and 3 are detail views of the communicating sleeves and some of the rock arms employed. Figs.` 4 and 5 are detail views showing the m-anncroi" telescoping or joining two parts of the instrument without obstructing the hole arranged at said point. Fi 6 is a cross section taken through the tue of the instrument and cutting one of the covers. This view shows a special form of construction for moisture from passing through the opening. F igs. 7, 8 and 9 are f detail views showing the manner of mounting the trill covers for convenient manipulation. Fig. l() A1s a cross section taken through the tube of the instrument at a pointA indicated by the line 10-1() Fig. 1 and showing the sleeves, shafts, communicating arms etc., in their radial relation to the tube. Fig. 11 isa detail view showing a special arrangement for compounding two covers. Fig. 12 shows another arrangement for compounding two covers. Fig. 13 is a detail View of Fig. 12 'showing an overlapping projection employed. Fig. 14 is a detail view showing a branch nger piece communicating with a cover. employed for automatically closing an auxiliary cover 'held open when playing the other covers ofthe lower octaves and retaining an open position when playing the auxiliary cover.' Figs. 16 and 17 are detail views showin" a special arrangement for conveniently a terr'iating between two covers.

In the `iig-fires of the drawing the reference numerals indicate the keys, closed covers, perforated covers and branch finger pieces,

and the reference letters indicate the shafts, .1

sleeves, and connections between said finger pieces, covers, etc.

Like 'numerals -and figures refer to like parts in the several views, and the present specification' is confined to these novel arrangements;

First. Referring to Figs. 1 and 11 the perforated cover is connected to a short sleeve C fitted on a shaft C, the sleeve C bein in turn connected with a rock arm g by the ar f, the rock arm g passing around the cover 6 and resting on a stop g soldered to the cover 5. The barf is secured to the sleeve C and oscillates about the shaft C. 'A stop f limiting the play of the covers 5 and 65 is se'- c'u'red to the sleeve C as shown.

Second. The arran 'ement of the mechanism as shown in detai in Fi s. 12 and 13 for the purpose of combining t e movement of the cover 50 with the cover 5. Upon the shaft z arranged parallel with thel shaft C and op osite the covers 5 and 50 is fitted a sleeve ivided into equal parts J and Jdpro` vided with overla ping projections m an m. The covers 5 an 50 are secured to the said sleeves. and normally held in their raised position by a spring r as illustrated by dotted lines in Fig. 12. By reason ofthe projection m resting beneath the projection m the cover 5 may be closed independently and at i;

Fig. 15 is a detail view of the means Fourth. The introduction of the auxiliary hole with cover 13 which is operated by a finger piece and facilitates the alternative fingering between the notes Gti and all the other notes. (See Figs. 1 and 1 5.) This cover 13 is mounted on the arm 14 pivoted at V. Resting beneath the arm 14 at the end opposite the cover 13 are rock arms V and V2. The rock arin V is rigidly secured to a sleeve V8 which is fitted on a short shaft V4 running parallel with theiiiain shaft C.

` Secured to the sleeve V" is the finger lpiece V 5.

The cover 13 would normally remain o en by reason ol'v the short spring V secure( to the under side of the pivoted aiin. 1 1, but the rock arin V which is acting under tension of the spring V 7 which is"'greater than the force of sprin'g V thus holds the cover 13 normally' in its closed position. This cover is closed, however7 while playing the lower notes by reason ol" the following: A small projection lw is soldered to the cover 6 on a line with the rock arm yw. The rock arin w is rigidly se` cured to the sleeve wi which is fitted over the short shaft V4 and adjoins the sleeve V". The rock arm w is secured at one end of the sleeve w and has its lree end resting beiieath the lug w. Secured to the opposite end ol the sleeve w3 is the rock arm V2 the free end of which restsbeneath the pivoted arm 14. lt will be seen that by this arrangement the covei' 1.3 may be held in its open position by pressing the fmger piece V`rl (the position shown in Fig. 15) While at 4the same time, should any of the lower notes be operated and with them the cover 6, the cover 13 would be automatically closed.

Fifth. The introduction of a supplementary trill key the cover of which is marked 10 and its manipulating finger piece 100. This key is independent of the main key7 Whose covers are marked 8 and 9 but for convenience of operation, the mounting and con municating finger ieees have been arranged as shown in the ra'wing. The supplementary cover 10 is rigidly secured to a sleeve d5 (see Fig. 7). This sleeve 'd5 is also fitted upon the shaft d resting parallel with and spanned by the oscillating shaft d4. The cover 10 is secured to one end of the sleeve d5 and its finger piece 10() is rigidly secured to its other end.

Sixth. An arrangement for overcoming fork iingering. To accomplish this purpose I have mountedthe covers 3, 4 and 12 as shown in Fig. 1 and in detail in Figs. 16 and 17 in which the cover 3 is shown rigidly coiinected to the main shaft C anddii'ectly operated by the finger piece 55. This cover 3 is also indirectly operated with the cover 4 and 60 v perforated cover 12 by the manipulation off the finger piece 120 which is arranged as :tolff lows: The finger piece 120 is rigidly secured; to a sleeve g littedover a short shaft g. The

cover 12 is rigidly secured to said'sleeve g and '65 is normally closed. A rock arin gi* is also rigidly secured to the sleeve g and has its li'ce end resting beneath the rock arm g3. An oscillating shaft h communicates the motion of the rock arin g to a short sleeve it '70 to which the perforated cover 4 is secured. When operating the cover fl through the mechanism just described, the cover 3 is carried with it by means ol a projectionlug h mounted on the sleeve-715* which is secured Eighth. The manner of telescoping or joining two parts of the instrument without obstructing the The parts have each formed therein res ectively registering holes 2() and 131. The iole 20 in the inner section is cut larger than the hole 21 so as to permit a limited rotation of one tube upon the otherwithout reducing or 95 obstructing its note-producing function.

Having thus described my invention, what lclaimis: l

A flute having telescoping parts provided with re istering holes, the inner hole being 100 larger t ian the outerliole to permit adjustment of said parts, substantially as' shown and described.

In testimony whereof I allix my signature in presence of two Witnesses. a
